Help! Early Browning pistils and purple leaves

[TentGrow]

Day 52 of flower, 1 plant has browning pistils, and slow/no new growth on buds.
Other plants have leaves curling up, brown spots and purpling, mostly on top leaves.

Hey tentgrow,
Do you have a little scope/ jewellers loop? So you can get a close up look at the trichomes. It may well be that it's close to the finish line.

Those leaves cupping up like that? What is the temp and humidity. She looks beautiful by the way. Don’t stress she is fine.

they are maturing out.
still some lingering white pistils, so i'd venture you are at final two wk swell, or just past.
look like most of what is gonna be there is there now. just watch for ripe.

edit : looks good too by the sugar etc.
